Touch Probe A touch probe is a precision sensor used in 3D printers for automated bed leveling, part alignment, and dimensional inspection. It detects the exact position of the print bed or model surface, ensuring accurate Z-offset calibration and consistent first layers. Touch probes enhance repeatability, dimensional accuracy, and surface finish. They are particularly useful for complex geometries, multi-material prints, and high-precision components. Advanced printers use capacitive, inductive, or mechanical touch probes for versatile material compatibility. Proper calibration ensures reliable measurements and high-quality prints. |
